Radiographic Testing, one of our core areas of expertise, calls for using x-rays or gamma radiography to perform full volumetric inspection to validate the integrity of welds and other components. Radiography is one of the oldest and most widely used non-destructive testing methods.

In most cases, radiographic testing is used for the evaluations of welds on pipelines, pressure vessels, piping, storage containers, and structures. JANX’s qualified radiographers interpret radiographs to applicable codes and standards such as API, ASME, and AWS while complying with required customer specifications.

JANX regularly provides high-production weld inspection services on major pipeline construction projects using both Real Time Radiography and Conventional Film Radiography, including internal crawlers.

Radiography is performed in accordance with applicable NRC, agreement states, or jurisdictional requirements.

Available radiographic equipment includes:

  • Gamma Sources – Iridium 192, Selenium 75, and Cobalt 60
  • External X-ray Tubes – 150kV to 300kV and can be used for various applications.
  • Internal X-ray Crawlers – 100kV to 300kV with pipe diameter ranges of 6” to 56”

JANX utilizes a wide range of radiographic techniques including:

Benefits

  • Provides a permanent record: Ensure compliance with codes and standards
  • Allows for full volumetric inspection: Allows customers to make informed decisions about weld or component integrity.
  • High probability of detection: Can detect porosity, inclusions, cracks, and voids in the interior of welds.
  • Provides accurate location of defects: Customers can quickly proceed with repairs, avoiding costly project slowdowns.
